Re: Which way for Speed Rings!

Washer and rings are press-cut with a several ton die, that can usually cut hundreds in one press drop.

In the case of the speedrings, it is in contact with metal on both sides and will not do the same damage as the sharp side of a bushing washer.

If you are using precision trucks or axles that have a tight radius shoulder you may have the bearings or speedrings jam on the axle, so in the case of precise axles, have the sharp edge on the bearing and the round edge on the axle-to-hanger shoulder

We usually keep the round side on the bushing when it comes to flat washers.
In the case of cupped washers, the sharp side is larger than the diameter of a bushing and will not damage the bushing, unless a larger (non-stock) bushing is used like Venom Eliminators, these do get cut up on cupped washers, but perform just as good if not better without washers. In this case I am referring about the bushing that is squished between the baseplate and the hanger.

I'm sure there must be a purpose to the round side versus the flat side, otherwise they would have made speedrings with two flat sides.

The ultimate goal is to make sure the wheel doesn't have any torsional motion. The rounded side obviously has a smaller contact patch than the flat side. If you have the rounded side facing the inner race of the bearing, the contact region of the speedring might not interact correctly with the inner race of the bearing, giving you the potential for some torsional movement. Whereas if you have the rounded side facing the faced hanger, there's a much wider contact patch for the round side to interface with, and the flat edge of the speedring is more consistently interfacing with the inner race of the bearing.

This being the case, the speedring between bearing and nut should also have the flat side pointing toward the bearing. In conclusion, both flat sides of the speedring should contact the inner race of the bearing.

I'm assuming this would allow us to have an even more precise and therefore more stable (slightly so, but still more precise and stable) ride.

Thanks for the help that all makes sense, appreciate the input and help.

Re: Which way for Speed Rings!

The truth of it all is that there are different sides of a speed ring and I would assume that they wouldn't make it that way if it didn't need to be. For all you haters who say it's a stupid question, answer that as to why the sides are different? I understand it may not make a difference but they do in fact have different sides.
